STONE LIFTING AND CARRYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 422,826, dated March 4,1890.

Application filed March 25, 1889. Serial No. 304,644. (No model.)

To all whom it may concern:

Be it known that I, JOHN IV. PETERSON, a subject of the King of Sweden,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in a Stone Lifting andCarrying Machine, of which the following is a full, clear, and exactdescription, that will enable others to make and use the same, referencebeing had to the accompanying drawings, forming a part of thisspecification.

The object of this invention is to provide a machine to be used inlifting, moving, and laying the foundation-stones of a buildingstructure.

Figure 1 is an end elevation of a machine embodying my improvedfeatures; Fig. 2, a side elevation, and Fig. 3 a detached detail.

Referring to the drawings, A represents the trestle-work supporting thetrack-ti1nbers A, and A A the track-rails.

The truck-frame consists of the mortised corner-pieces B, connected onthe sides by the horizontal framing-timbers B, mortised into the innerfaces of the pieces B, the cornerposts B mortised into the upper ends ofthe pieces B and supporting the cross-bars B on their upper ends and thediagonal braces B The cross-bars B are provided with trackrails a, onwhich the carriage 0 travels. The

'top side bars 0 prevent the carriage C from running off of the ends ofthe track.

The carriage C consists of the two end plates a a, between which thelifting mechanism is located and supported, and the carriage-wheels amounted 011 the axles a journaled in the lower edge of the end plates.

The winding-drum D is journaled in the end plates of the carriage andhas the gearwheel a mounted on one end thereof. This gear-wheel engageswith the pinion a mounted on one end of the counter-shaft a, locatedabove the winding-drum. A gear-wheel b is mounted on the opposite end ofthe countershaft, which in turn engages with the pinion 11', mounted onthe hand or crank shaft 12 One end of the hoisting rope or cable Uissecured to the winding-drum and is then rove through'the tackle=-blocksb b, the opposite end being secured to the upper block. The clevis b issecured to the lower block and re ceives the upper ends of the chains cld, the lower ends of which are provided with grappling-hooks d d,engaging the object to be lifted, as shown in Fig. 1.

The brake-strap E encircles apart of the winding-drum and has one endsecured to the pin (Z inserted in one side of the carriage, and theopposite end secured to the innerend of the hand-brake lever (i pivotedon the rod (1 by which arrangement the operation of lowering the stoneis controlled. The pawl (Z serves to lock the mechanism against a backmovement.

Each end of the machine is provided with a platform cl for theconvenience of the workmen in operating the machine.

The truck-wheels d" are journaled in the lugs (1 formed on andprojectingdownwardly from the corner-pieces B, a detached View of onebeing given in Fig. 3.

In operation the track will be laid along the line of the foundation andsupported 011 suitable trestle-work. The stones may be picked up at thepoint on the outside of the building where they are unloaded, and easilyand quickly transported to the place where they are to be laid in thewall, and by means of the traveling carriage on the truck-frame thestone can be conveniently placed in the exact spot and quickly raisedagain should it not be exactly level at first. By rotating thehandshaft, by means of the handle g, motion is transmitted to thewinding-drum through the system of gear-wheels described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a stone-lifting machine, the truckframe consisting of the mortisedcorner-pieces B, provided with downwardly-projecting lugs (Z betweenwhich the truck-wheels are journaled, the horizontal framing-timbers B,the corner post B mortised in said corner-pieces, the cross-bars B andthe diagonal braces B, substantially as set forth.

2. In a stone-liftingmachine, the combination of the main or truckframe, the traveling carriage supported thereon and consist ing of thetwo end plates mounted on wheels, the winding-drum journaled in andlocated between said end plates, the gear-wheel mounted on said drum,the counter-shaft, the pinion mounted on one end thereof andengagingwith the gear-Wheel 0n the winding-drum, the gear-wheel mountedon the opposite end 5 of said counter-shaft, the hand or crank shaft,

the pinion mounted thereon and engaging with the gear-wheel on thecounter-shaft, the
